    摘要: A method for determining a crash condition of a vehicle comprises the step of sensing crash acceleration in a first direction substantially parallel to a front-to-rear axis of the vehicle and providing a first crash acceleration signal indicative thereof. The method also comprises the step of sensing crash acceleration in a second direction substantially parallel to a side-to-side axis of the vehicle and providing a second crash acceleration signal indicative thereof. The method further comprises the steps of determining a crash metric value functionally related to the sensed crash acceleration based on the second acceleration signal and comparing the determined crash metric value as a function of the sensed first crash acceleration signal against an associated threshold. The method still further comprises the step of determining a crash condition of the vehicle in response to (a) the comparison and (b) the first acceleration signal.

    摘要: An apparatus and method for controlling an actuatable occupant restraint device having a plurality of actuatable stages (24, 26), the apparatus including a crash sensor (14, 16) for sensing crash acceleration and providing a crash acceleration signal indicative thereof. A controller (22) determines a velocity value (74) and a displacement value (80) from the crash acceleration signal. A safing function controls enabling and disabling of a deployment control circuit in response to the determined velocity (74) and displacement (80) values. A displacement based velocity threshold (133) and a displacement threshold value (125) define an immunity box. The velocity threshold value (133) varies as a step function of displacement. If the velocity/displacement values are within the immunity box, the safing function is in a disabling condition. If either value is outside of the immunity box, the safing function is in an enabling condition. A side impact sensor (28) and side impact crash event circuit (122) determine if a side impact crash event is occurring. If a side impact crash event is occurring, the threshold values (125, 133) of the immunity box are adjusted.

The control signal (136, 174, 176) has a value that varies as a function of the value of the second sensor signal and at least one of the received first sensor signal and the determined default value of the first sensor signal.

    摘要: The present invention is directed to an apparatus for controlling a vehicle actuatable occupant restraining system including a discrimination crash sensor (32, 34, 36) for sensing a vehicle crash condition and providing a discrimination crash signal indicative thereof. A first crush zone sensor (40) is located at a first vehicle crush zone location and provides a first crush zone signal indicative of crash acceleration sensed by the first crush zone sensor. A second crush zone sensor (42) is located at a second vehicle crush zone location for providing a second crush zone signal indicative of crash acceleration sensed by the second crush zone sensor. A crush zone safing determining function (218) of the controller (50) monitors the first crush zone sensor and the second crush zone sensor and provides a crush zone safing signal in response to one of the first and the second crush zone sensors signals exceeding a first threshold and the other of the first and the second crush zone sensors signals being faulty. The crush zone safing signal is also provided in response to one of the first and the second crush zone sensor signals exceeding a second threshold, the second threshold being greater than the first threshold. A controller (50) monitors the discrimination crash signal and the crush zone safing signal for controlling an actuatable restraining device in response thereto.
